摘要

RATIONALE:The HLH-94 protocol is a standard induction treatment for hemophagocytic lymphohistiocytosis. However, about 30% of patients may not respond. Ruxolitinib has been clinically proven to be an effective treatment for hemophagocytic lymphohistiocytosis (HLH).PATIENT CONCERNS:A previously healthy 14-year-old girl presented to the local hospital with a 4-day history of persistent fever and sore throat.DIAGNOSIS:Clinical and laboratory tests revealed fever 38.5°C, hepatosplenomegaly, pancytopenia, hypertriglyceridemia, hypofibrinogenemia, hyperferritinemia, and an elevated interleukin-2 receptor level.INTERVENTION:This patient was treated with ruxolitinib and the HLH-94 protocol.OUTCOMES:The patient's clinical and some laboratory indices improved. Unfortunately, vital signs such as respiratory function and consciousness did not improve.LESSONS:This case report highlights the effect of using ruxolitinib in conjunction with the HLH-94 protocol. However, safety evaluation of this regimen was not performed because critically ill patient died too fast.Copyright ? 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
